To @ZZ whom it may concern.'

Be it known that I, CHARLES M. BROWN, a citizen of the United States ofAmerica, and a resident of Melbourne, in the county of Marshall andState of Iowa, have invented new and useful Improvements in SubmergedPumps, of which the following is a specification.

My object is to facilitate the operation of a double-acting force-pumpas required to elevate water in a continuous stream by means of areciprocating plunger in a straight cylinder at the bottom of a well andoperating mechanism at the top of the well.

My invention consists in the construction and combination of a cylinderhaving a tube or bore extending parallel with its wall, chambers at itstop and bottom to receive valveoperating devices, a detachablecylinder-bottom having an anchoring device formed integral therewith,and a plunger, as hereinafter set forth, pointed out in my claim, andillustrated in the accompanying drawings, in which- Figure lisalongitudinal sectional view, and Fig. 2 a transverse section, of mycomplete invention.

A represents a metal cylinder, that may vary in diameter and length asdesired. It has a solid closed top and a flange at its open bottom.

B is a tube formed integral with the wall of the cylinder A.

C is a vertical extension and duplex-valve seat at the side and top ofthe cylinder, through which the bore of the tube B extends.

d is a bore or eduction-port and valve-seat in the extension O, whichextension is screwthreaded at its top and adapted to form a joint with asection of a well-tube, as clearly shown in Fig. I.

f is an eduction-port at the bottom of the cylinder, that opens into thetube B. An enlargement in the lower end of the tube B and a cavity inthe bottom of the cylinder facilitates the flow of water from thecylinder into the tube.

No. lis an induction-port at the top and side of the cylinder, and N o.2 a corresponding port at the bottom of the cylinder. Checkvalves g incurved inlet-pipe are screwed in the-ports Nos. l and 2 in such a'mannerthat they will be alternately opened and closed by (No model.)

the operation of the plunger and the pressure ofthe water outside of thecylinder. ,i

J represents a plunger fixed to a rod, n, that extends up through anangular' bore or stuffing-box, o', at the center of the closed top ofthe cylinder, that will allow vertical motion to the rod ofcorresponding angular shape, but prevent rotary motion, as required toretain the valve-operating devices s, carried at the top and bottom ot'the plunger, from getting out of line with the ports Nos. l and2 and thechambers 71., which they alternately enter as the plunger isreciprocated in the cylinder.

T is a detachable bottom fixed to the flange ofthe open end of thecylinder A. A rim orv disk, V, and pointed pegs fr are formed on orfixed to lthe rim or' disk, to project downward to engage the bottom ofa well, for the purpose of anchoring the complete pump, as required, toprevent the cylinder from slipping about in the bottom of the well. v Inthe practical use of my invention I combine a well-tube with theextension C at the top of the cylinder A, and then let the bottom of.the complete device down into a well, and allow the pegs x to sink intothe ground, to serveV as an anchor in holding the cylinder stationary.The plunger-rod, that extends to the top of the well, I connect withmechanism adapted to be operated by hand to impart a reciprocatingmotion to the rod and the plunger on its end and within the cylinder insuch a manner that each downward stroke of the plunger will close thevalve in the port No. 2, and force the water in the lower half of thecylinder through the eductiOn-port f and up through the tubeB into thewell-tube, and as quick as the downward stroke is completed the valve inthe top of the tube B will close and prevent the water from fallingback, and each upward stroke of the plunger will close the valve No. land force the water in thel An improved pump, consisting of the cyl-linder having a closed top and flanged open IOO bottom, an integral andparallel tube, B, :L and the lower end of the tube,snbstantiallyasvertical extension, C, having a port or bore, shown and described.
